An event due to be held in central London about how the world can adapt to extreme heat has been cancelled due to soaring temperatures.
Wednesday's meeting - titled Extreme Heat: Improving governance and strengthening action around the world - was to have been held at the London School of Economics' Shaw Library as part of London Climate Action Week.
Organisers said the university's building did not have any cooling mechanisms in place "like most buildings in London".

red warning for extreme heat in London and other parts of England is in place until 23:59 BST on Thursday, with temperatures forecast to hit up to 37C.
A spokesperson for the organisers, the Zurich Climate Resilience Alliance, said they could not risk the wellbeing of attendees.
"The magnitude of future impacts from extreme heat will largely depend on global mitigation efforts, local heat governance, and response plans," the spokesperson said.
"Cities like London have unique potential to adapt to changing heat risks through effective risk management at multiple levels, connecting policies and incentives, and strengthening community adaptation capacity."
